SPRING-WHEEL FOR VEHICLES.

in the art to which it appertains to make and use the same.

This invention relates generally to ve-' hicle wheels, and more particularly to that class of wheels which are elastic or yield able between the hub and tire.

The primary object of the invention is to provide a wheel of this character having an improved form of spoke which is so constructed and arranged as to provide a maximum amount of resiliency, and to this end it consists of a series of spokes of approximately sinuous form arranged between the hub and rim.

Another object of the invention is to pro-' A11 additional object resides in the pro vision of a device which will be simple, strong, durable and inexpensive in construction, eflicient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings in wh1ch similar reference characters designate like parts throughout the several views: Figure 1 is a front elevation of a resilient wheel constructed in accordance with this invention; Fig. 2 is a side elevation of the same; Fig. 3 is a Vertical sectional View taken on the plane of the line 3-3 of Fig. 1; and Figs. 4: and 5 are vertical sect onal vlews through one of the spokes, showlng particularly the means of connection of the same to the rim sections and hub respectively.

M Referring more particularly to the drawmgs, the numeral 1 designates the body portion of the hub of a wheel constructed in accordance with this invention. This body portlon 1 is preferably made of wood and is provided with a centrally arranged bore 2 having a metallic lining 3 therein, one of the ends of the lining 3being provided with ears 4 adapted to be engaged by suitable fastening' elements to retain said lining in place. Arranged on the outer sides of the body portion 1 in any suitable manner is a cylindrical metallic casing 5, the ends of which are provided with attaching elements to be engaged by the inner ends of the spokes of the wheel. These attaching elements are here shown in the form of cir-,

cumferentially spaced lugs 6 which are struck inwardly from the ends of the casing 5 and having slots 7 arranged in their Extending from the hub of the wheel is a double series of spokes comprising substantially a plurality of spaced pairs of sinuous or zig-zag resilient strips 8. The inner ends of these strips 8 are reduced in width to form tongues 9 which are extended through the aforesaid slots 7 and then bent inwardly upon the lugs 6, thereby firmly securing said strips to the attaching elements. The outer ends of the strips 8 are integrally connected by transverse bars or straps 10, and

secured to these straps 10 is a pair of spaced rim sections or rings 11. These rim sections 11 are here shown as being clamped and secured between the inner sides of the straps 10 and the outer folds of the strips 8. The rim is adapted to receive a solid rubber or other suitable tire (not shown).

'Disposed between the spokes or strips 8 are diagonally crossed braces 12, the ends of which are connected to the upper and lower inner folds of the strips in any convenient manner. This it willbe readily understood prevents the spokes of the rim from shifting longitudinally with respect to the hub, but allows a free yielding move ment of the arm.

From the foregoing description, taken in connection with the accompanying drawings, the operation and construction of the invention will be readily understood without a more extended explanation.

As various changes in form, proportion and the minor details of construction may be resorted to without departing from the spirit of the invention, I do not wish to be limited to the construction herein shown and described other than that set forth in the appended claims.

I claim:

1. A Wheel of the class described comprising a cylindrical hub, a cylindrical casing surrounding said hub, circumferentially spaced lugs struck inwardly from the ends of said casing and having slots arranged in their bent portions, a rim, and a plurality of resilient strips disposed between said hub and said rim and having their outer ends connected with the latter, the inner ends of said strips being reduced in width to form tongues, said tongues being extended through the slots in said lugs and then bent inwardly upon the same.

2. A Wheel of the class described comprising a hub, a double series of sinuous resilient strips extending radially from the ends of said hub, transverse straps disposed between the outer ends of said strips and integrally connected with the same, and a pair of spaced rings clamped and secured between the inner sides of said straps and the outer folds of said strips.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
